APPARATUS FOR CLEANING YARN.

Application filed September 24, 1913.

To all whom it may concern Be it known that I, EMn. Pmnn, subject of the King of Prussia, German Emperor, and resident at Hanover, in the Province of Hanover, Kingdom of Prussia, German Empire, have invented certain new and useful Apparatus for Cleaning Yarn, of which the following is a specification.

As is well known, weaving yarns especially those of flax, hemp or jute as also cotton are liable to have attached, numerous strawy and other vegetable fragments which injure the fabric and should conse- ({uently be removed before the yarn is woven. In this process ofv removal, however, it is very desirable that the small filaments adherent to the yarn shall not be removed along with straws or other foreign bodies because these little filaments are desirable to be woven into the fabric inasmuch as they add to its quality.

The object of the present invention consists in a new and practical arrangement for the cleaning of yarns. In accordance therewith, a series of rough bodies are freely suspended between which the threads are guided inclose contact. It is moreover advantageous to support the cleaning bodies in a liquid through which the filaments pass. The cleaning bodies themselves are preferably formed of wood or other light material in order to make them as light as possible, which material is covered with some hard substance such as Naxos emery or the like. B y an arrangement of this kind, the threads are easily separated from the adherent strawy filaments and the like Without any injury. By the free suspension of the cleaning bodies any breakage of the filaments is prevented, because the suspended bodies can easily move apart] Preferably, the filaments are somewhat shaken onset in motion by suitable mechanism, and consequently impelled frequently against the surround ing cleaning bodies. 011 the passage of the filaments through the liquid receptacle in which also the cleaning bodies are immersed, a specially favorable action is obtained, inasmuch as the liquid imparts to these bodies a greater inertia, so that they only move away to a very slight degree on contact.

Specification of Letters Patent.

Serial No. 791,539.

In order that the light bodies shall not float upward in the liquid, they are weighted to the requisite degree.

In the accompanying drawing is illustrated diagrammatically a construction of the invention.

The filament a passes over the rollers b, 0 (Z through the liquid receptacle 6. Close around the parts of the filament which dip into the liquid there are freely suspended on strings the cleaning bodies f'and brought as near. as possible without entire contact to the filaments.

The filament is preferably guided vertically into the receptacle because in this manner the cleaningbodies can be suspended at various heights close around the filaments. Obviously, there are also other arrangements possible. In order to shake the filament about, it can on entrance into the liquid, and if needful also at other points during its passage be seized by suitable little levers provided with loops and caused to oscillate. For the same purpose also the rollers might be caused to move about, over which the filament passes.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is f 1. Apparatus for treating yarn comprising a tank, rolls for supporting and guiding the yarn in transit through the tank, and floating bodies in theline of travel of the yarn and on opposite sides thereof.

2. In apparatus for treating yarn having a liquid holding tank and rolls for supporting and guiding the yarn through the liquid in the tank, bodies having roughened surfaces freely suspended in the liquid and in the line of travel of the yarn, to remove by friction the extraneous fibers from the yarn.

In testimony, whereof I have signed my name to, this specification in the presence of two subscribing witnesses.
